Section 550.1154 - How do I determine if my reservoir is sensitive?(a) You must determine whether each reservoir is sensitive. You must classify the reservoir as sensitive if: (1) Under initial conditions it is an oil reservoir with an associated gas cap;(2) At any time there are near-critical fluids; or(3) The reservoir is undergoing enhanced recovery.(b) For the purposes of this subpart, near-critical fluids are:(1) Those fluids that occur in high temperature, high-pressure reservoirs where it is not possible to define the liquid-gas contact; or(2) Fluids in reservoirs that are near bubble point or dew point conditions.(c) The Regional Supervisor may reclassify a reservoir when available information warrants reclassification.(d) If available information indicates that a reservoir previously classified as non-sensitive is now sensitive, you must submit a request to the Regional Supervisor to reclassify the reservoir. You must include supporting information, as listed in the table in § 550.1167 , with your request.(e) If information indicates that a reservoir previously classified as sensitive is now non-sensitive, you may submit a request to the Regional Supervisor to reclassify the reservoir. You must include supporting information, as listed in the table in § 550.1167 , with your request.
